ST31000528AS - SMART Interpretation needed

[gacekssj4]

Hello,
(really fast responce appreciated)
I wanted you to see my SMART status, I don't have many experience with hard disks and not sure if i should trust smart. Know what I write can mean its obvious my disk is broken, but want your advice
My windows keeps asking for backup all time. Is it the end of its life?

To addition, just before erros he started to give some strange buzzing noise sometimes. but after a while it stops. Can't describe it, its like smth really quickly hitting spinning platter?

ST31000528AS (9VP51XND)

What do you think about this?

PS Where can I find information about F1 and F2 value? couldn't google it.

Edit: Moved smart to more readable format in txt. Open with windows notepad for best view

Seems i can't edit post anymore. Since i forgot to put one question more i wanted.

I never cooled my hard disks. I have 3 disks in 3 disk slots. The one posted above is in the middle. Is it possible that my problems come from overheating drive? Temperature between disk is about 36 C. (put between them case thermal sensor)

I don't know much about data recovery (I'm learning), but I can tell you in a 65-70 degree room, 20-250GB drives run about 85-90 degrees on an open bench (not enclosed) measured with a thermal gun. A 500 GB drive runs 98-100 degrees on an open bench. so 96-97 degrees in an enclosed area I think would be normal temp.

Yes.

As well as many sectors already reallocated, some sectors are currently unreadable (SMART attribute 0xC5). If you want any data from this disk, then you should copy that data now and then stop using this disk drive. You might be able to sell the drive PCB on eBay etc.

Due to the known currently unreadable sectors, you might not be able to successfully copy all files from the drive (depends whether the unreadable sectors are part of files or not). There are different ways of copying the needed data from that drive - copy by file, or clone the whole drive. There are advantages & disadvantages to each method.

If you are unable to read data which is really required, then some pro DR data extraction equipment might be more successful.

HDD is still working, i've been copying data since yesterday just to be sure. 100% of what i needed got copied ( only program files got corrupted but there was nothing there beside some IRC clients etc). So no data loss

As well as many sectors already reallocated, some sectors are currently unreadable (SMART attribute 0xC5)

On my list is it 05 (Reallocated Sector Count) or C5 (Current Pending Sector )?

I bought this disk exacly 1 year ago, and got 36 months warranty. Will give it back to shop so they can send to analyze and give me replacement ( hope they wont try to fix it ).

Hope failure like this is included in warranty. I haven't moved this computer ( nor Hdd ) for more than 3 months. So it's production fault

Btw, before i send it back, should i try to erase (overwrite sectors with random values) all data so it can't be recovered? ( had some important data there like online shops source codes and database dumps - along with personal information of cliets of those shops ).

Good

The currently unreadable sectors are those shown in attribute 0xC5, as I explained; those sectors already reallocated are shown in attribute 05.

I hope you are correct about the length of warranty on your drive. That 36 months sounds like the warranty of a typical retail Seagate drive - not all drives which are sold, have a full Seagate retail warranty (many shops sell OEM drives, which do not have the full Seagate warranty). If this drive has a full Seagate warranty, then you might be able to RMA the drive direct to Seagate, depending on arrangements in your country.

I recommend that you run the SeaTools testing utility from Seagate, after you have read the data you need from the disk. That should give you a failure error code, which can be used to prove to Seagate or the shop, that the drive is faulty.

Btw, before i send it back, should i try to erase (overwrite sectors with random values) all data so it can't be recovered? ( had some important data there like online shops source codes and database dumps - along with personal information of cliets of those shops ).

Yes, if you're going to return the drive, then trying to remove data is a good plan. There are several possible utilities you can use inc SeaTools, HDDErase (to use the drive's internal Secure Erase functionality - this is probably what I would use), or just using dd to write from /dev/zero. You don't need to overwrite with random values; with modern drives, a zero fill is just as effective (read the updated Guttmann analysis for confirmation).

However, if you are storing very sensitive data on a disk, you should consider either being prepared to never return even faulty disks (just accept the cost of never returning disks, and using extreme physical destruction of the platters e.g. shredding), or else using full disk encryption and then "lose" the encryption keys before returning the disk. In these ways, you don't have to worry about any "old" data in the (now) reallocated sectors, which normal overwrite techniques will not erase, and a DR company would be able to read those sectors.

P.S. Remember to make backups.

Have fun

I can't see 0xC5 attribute there. Only 05 and C5.

Any freeware tool that makes erasing miracles happen?

What about linux command i found

dd if=/dev/urandom of=/dev/sda bs=1M

This is not important for your original question of "is my disk at end of its life" but here's a hint: Have a read about hex numbers, and how they are usually written, and you'll understand what I'm saying

Any freeware tool that makes erasing miracles happen?

That depends what you mean by "miracles". The utilities which I mentioned before, are all free.

What about linux command i found

dd if=/dev/urandom of=/dev/sda bs=1M

As I explained before, use of random overwrite is not required, and depending on your host, using /dev/urandom may be slower than use of /dev/zero, but it's your choice.

You will need to check the correct Linux device name for the faulty disk on your system - it might, or might not, be called /dev/sda.

Thank you for help

Somehow missed that part ( somone called me in middle ).

Warranty is 36 months - that's what is on my invoice . Handled by shop ( they send it to producer ).

Goint to erase it now and send for replacement Keep thumbs up
And thx for help again

Thank you for help

You're welcome - good luck
